<p>I get spurious <code>undefined reference</code> errors when building rustc, pretty much daily. They're always to these <code>anon</code> symbols:</p>
<div class="codehilite"><pre><span></span><code>         /home/tgnottingham/Projects/rust/rust/library/core/src/option.rs:386: undefined reference to `anon.04b56f81f8d51f30b8720ce746e686ac.0.llvm.4938662292890509205&#39;

          /usr/bin/ld: final link failed: bad value
          collect2: error: ld returned 1 exit status
</code></pre></div>
<p>Of course it always happens at the end of compilation, so it's a real drag. I generally have to <code>rm -r build</code> to get past it (<code>./x.py clean</code> doesn't seem to do the trick). Does anyone else run into this?</p>

<p>Seems like it might be related to LLVM - that's why <code>./x.py clean</code> doesn't work (IIRC, <code>./x.py clean</code> doesn't remove LLVM)</p>

<p>Discussed this a bit with <span class="user-mention" data-user-id="232545">@Joshua Nelson</span> in <a href="https://github.com/rust-lang/rust/issues/79946">#79946</a>.</p>
<p>It seems like this is highly likely to be related to rust-analyzer running in the background during compilation. The problem only occurs for me when I'm editing source during compilation and I have rust-analyzer going.</p>

<p>but my point is that similar errors <em>also</em> appear for <a href="https://github.com/rust-lang/rust/issues/76661">https://github.com/rust-lang/rust/issues/76661</a> and whatever <a href="https://github.com/rust-lang/rust/issues/79946">https://github.com/rust-lang/rust/issues/79946</a> is, so I don't think they're all the same root cause</p>
